CASING FOR PIPES.

SPECIFICATION forming part of Letters Patent No. 308,228, dated November 18, 1884.

Application filed May 24, 1884. (No model.)

JOHN F. W001), both of \Vilmington, in the county of New Castle and State of Delaware, have invented a new and Improved Casing for Pipes,'of which the following is a full, clear, and exact description.

The object of our invention is to provide a new and improved casing for holding nonconducting niaterialsuch as mineral wool, 8tc.on pipes, which casing can easily be applied and fitted, and can be closed and locked without requiring the use of solder.

The invention consists *in the combination, with disks adapted to surrounda pipe. ofopen tubular casing-sections surrounding the disks. and each provided at one longitudinal edge and at one end with a pocket. The free edges of the sections are held together by means of nails, pins, 8m.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

a sectional plan view of the same on the line a: 00, Fig. 1. Fig. 3 is a plan View of one of the sections, showing one end edge and the section being opened.

A disk, A, is provided with a central aperture adapted to receive the pipe, B, to be incased, and the outer diameter of the disk A is equal to the inner diameter of the casing O, which is to hold the non-conducting material around the pipe B. The disk A is cut open to permit placing it on any desired part of the pipe B, and preferably has its outer edge bent down to form aflange. A series of apertures, D, or slots are punched in the disk A,to allow the non-conducting material in the different compartments to unitetliatis,the strands and fibers ot' the non-conducting material can be partly in one chamber and partly in another,

Apertures a are formed in. the open edges of the tube or casing sections, and when the edges of the section are overlapped a pin or nail, G, is passed through the apertures a, thus holding the edges of the tube-sections together and closed. The tube or casing sections can thus be opened very easily to pass them around the pipe B and to fill in the nonconducting or filling material. The casingsections are held concentric with the pipe B by the disks A.

Means must also be provided for uniting the adjoining ends of the sections, and for this purpose one end edge of each section is creased to form an annular pocket, H, for receiving the adjoining edge of the next section of the casing.

If a pipe is to be provided rith a non-conducting covering, a series of disks, A,is placed around the pipe, casing sections are passed around the disks A, the free edges of the said sections being passed into the pockets F, the casings are closed and locked by means of nails G, pins, 810., and then the sections are filled with the non-conducting material.

When a section is filled, another is placed adjoining it, the edge of the one section passing into the pocket in the edge of the other section, and so on.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. In a casing for pipes, the combination, with disks fitting on the pipes, of tubular casings made in sections and fitted around the disks, substantially as herein shown and described.

2. In a casing for pipes, the combination, with the disk A, of the open tubular casingsections E, each having one edge creased to form a pocket, F, along the edge, which pocket is to receive the oth r edge, substantially as herein shown and described.

3. In a casing for pipes, the combination,
